            <title>[SERVER-65315] Prevent split concurrent with tenant migration or merge</title>
                <link>https://jira.mongodb.org/browse/SERVER-65315</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Each of tenant migration, split, and merge already disallow concurrent instances of their same type.&lt;/p&gt;

&lt;p&gt;Additionally, &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-59786&quot; title=&quot;Prevent concurrent merges&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-59786&quot;&gt;&lt;del&gt;SERVER-59786&lt;/del&gt;&lt;/a&gt; disallowed a tenant migration concurrent with merge.&lt;/p&gt;

&lt;p&gt;This ticket is to disallow split concurrent with tenant migration or merge, after which we&apos;ll have fully implemented the concurrency restrictions.&lt;/p&gt;</description>

&lt;p&gt;The lock document would be inserted after the state document (to ensure the POS will resume it when stepping up) but before the access blockers are created (they would be created in the AbortingIndexBuild phase). If the lock document cannot be inserted, we need to abort the instance.&lt;/p&gt;

&lt;p&gt;This change also means we need to be careful about access blocker removal when deleting the state document as it might not be the owner of the blockers. We could start a split which insert blockers, then start another split which will fail right away as it can&apos;t insert the lock document. Removal of the second split state document could remove the blockers from the first split (if it&apos;s still ongoing). The idea to address that issue would be to add and remove blockers by migrationId (which is already done for shard merge).&lt;/p&gt;</comment>

There&apos;s a few points to take into consideration with this ticket :&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;TenantMigration/ShardSplit are different instances of PrimaryOnlyService (with different mutex)&lt;/li&gt;
	&lt;li&gt;We need to ensure mutual exclusion when calling getOrCreate (check if conflicting instance exist, then create and insert one while holding the lock)&lt;/li&gt;
	&lt;li&gt;My first though was calling one service from the other `getOrCreate` to check for conflicting instance
	&lt;ul&gt;
		&lt;li&gt;Difficult to ensure valid mutual exclusion for the whole operation (holding both instances&apos; locks from checking for conflict until insertion of the new instance)&lt;/li&gt;
		&lt;li&gt;It opens a possibility of deadlock (TMDS locks, then acquires split&apos;s lock. Split lock then acquires tmd&apos;s lock)&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;On option I thought about is to have another class (let&apos;s call it InstanceHolder for now) that holds the list of instances and creates them. Each PrimaryService would have one such class and delegate the creation of instances to it. ShardSplit and TenantMigration could share and InstanceHolder which could ensure no conflicting instances are created.&lt;/p&gt;

&lt;p&gt;We&apos;d have&#160;&lt;/p&gt;
